Electrochemical test electrode device applied to medium-temperature, high-salt and humid environment to realize stress loading

Abstract

The invention relates to the field of electrochemical testing of environmental systems under the action of multiple factors such as medium temperature, stress, multi-salt and humidity, in particular to an electrochemical testing electrode device applied to medium-temperature, high-salt and humid environments to realize stress loading. The working electrode is placed in an inner cavity of the quartz tube located on the inner side, the reference electrodes are placed in through holes in the upper surface, the lower surface and the bottom surface of the tube wall of the quartz tube located on the inner side, and the four reference electrodes with the same diameter are arranged around the working electrode; the counter electrode is placed between the two coaxial quartz tubes, and the counter electrode is annularly arranged around the working electrode in a surrounding manner; the cross-shaped fixing bracket is arranged in the groove of the working electrode, four edges of the cross-shaped fixing bracket respectively correspond to the semicircular and rectangular through holes and are matched with the semicircular holes, and the gasket and the stainless steel nut are sequentially mounted on the part, extending out of the semicircular and rectangular through holes, of the cross-shaped fixing bracket. The problems that a high-resistance severe environment formed by medium temperature and multiple salts is very difficult to realize testing and the like are solved.
